Current Omics Advancement in Plant Abiotic Stress Biology investigates the causal molecular factors underlying the respective mechanisms orchestrated by plants to help alleviate abiotic stress. Despite available knowledge of abiotic stresses in crop plants and high throughput tools and biotechnologies, in this book, a systematic effort has been made for integrating omics interventions across major sorts of abiotic stresses with special emphasis to major food crops infused with detailed mechanistic understanding, which would furthermore help contribute in dissecting the interdisciplinary areas of omics-driven plant abiotic stress biology in a much better manner. It focuses on the integration of multi-OMICS biotechnologies in deciphering molecular intricacies of plant abiotic stress, namely drought, salt, cold, heat, and heavy metals in major C3 and C4 food crops. Together with this, the book provides updated knowledge of a common and unique set of molecular intricacies playing a vital role in coping up severe abiotic stresses in plants deploying multi-OMICS approaches.
